Leave AC on or Buy a Dehumidifier When Storing Our RV?

Thanks for all the advice. We decided to purchase a dehumidifier but have already returned it. Two issues: the filter needed to be cleaned every two weeks and it put out a tremendous amount of heat. We also had concerns about leaving the unattended trailer plugged in during the long, thunderstorm ridden Florida summer. We're just going to leave the vent open and crack a window or two. We'll also use 3 of the large tubs of Damprid - they are advertised to last 6 months. Thanks again for all your input.
